I hope the GHC provide a JVM backend.

also:
1. GHC compile hs to bytecode(name as klass) like what
javac
and klass can be packed as kjar(like jar in java)

2. an KVM interpret the klass bytecode and translate it
to java .class, then execute it on JVM. the KVM can be
write in haskell also.

now, a pure java based GHC and KVM can be used on JVM like
1. ghc.kjar contains the ghc compiler
2. happy.kjar contains the happy compiler
3. kvm.kjar contains the KVM
4. kvm.jar contains the bootstrap kvm that can be run
on JVM.
